Specication of Letters Patent.

Patented June 7, 1921.

Application filed April 3, 1918. Serial No. 226,507.

To all whom it may concern:

Be it known that I,"DAV1D A. Dnonow, a citizen of the United States,residing at Buffalo, county of Erie, and State of New York, haveinvented certain new and useful Improvements in Pumps, fully describedand represented in the following specification and the accompanyingdrawings, forming a part of the same.

This invention relates to pumps, the especial object of the inventionbeing to provide a combined pump and condenser structure that iscompact, simple and economical.

yThe following specification describes and the accompanying drawingillustrates a lpump constructed in accordance with the invention, itbeing understood that changes may be made in the form, arrangement andconstruction of the parts without departing from the invention, the formherein shown being a preferred embodiment thereof.

In the drawing f Figure 1 is a view in side elevation, with parts invertical section, of apump embodying the invention; and i v Fig.`2 is across sectional view taken on the line 2-2 of Fig. 1.

Referring tothe drawing, a double acting centerpacked 'pump is shown,having the pulsation chambers 11 with the force and air chambers 10above them, and the casing 12 forming the common suction chamber 13below them, with the suction funnels 14 and suction pipe 15. The spaceabove the lower ends of the suction funnels form air spaces and as hereshown, separate air chambers are formed for the two sections by means ofa web or partition 16 and extending down into the suction chamber. I

Within the suction chamber 13 is a condenser, located in the path of thewater flowing through the chamber. As here shown, the condenser pipes 17are mounted in the sides of the casing 12 and open into common chambers18, 19, formed by caps 20, 21 secured to the casing. rihe exhaust steaminiet 2a and free exhaust pipe 25 connect with chamber 19, and thechamber 18 has the usuai outlets 22 and 23 for water of condensation andair.

Vhen the pump is operated, the water ficwing in from pipe 15 and throughthe suction chamber to thetwo intake funnels, passes over the condenserpipes. Thus the water being pumped is utilized as a cooling' medium forthe condenser for the exhaust steam from the engine that drives thepump. i.With this condenser within the casing that forms the suctionchamlier, and with the further feature of the air chambers described, astructure combining the pump, condenser and suction air chamber' isprovided which is extremely compact, simple and economical.

1Wha-t is claimed is: p 4 Y 1. The combination with a pump and Yitssuction chamber,`of means for forming an air chamber in the suctionchamber', and a condenser in said suction chamber with its condensingsurface Vlocated in the path of the water flowing through said suctionchamber.

2. In a. pump, the suction chamber 13, the suction funnels 14%, the web16 dividing the chamber between the funnels and the condenser pipes 17,substantially as described.

In testimon whereof I have hereunto set my hand.
